I've been looking at C-caching of Tcl dynamic content, with "dirty
cache" support. For example, replacing the Tcl code that returns a
user's uploaded photo with C code.
I wrote C code to do this, and got 14k/second vs 240/s for the same
tcl function. So, C really is a good replacement for Tcl when a
particular URL needs to be very fast.
My solution to that problem was simply caching in the filesystem and
serving static files. The way this works in a multi-server
environment is that the custom 404 handler figures out the request
was for "/photo/123/axbcgsfdt.jpg" and just grabs it from the
database, caches it and redirects back to it.
That way I get the convenience of Tcl code and the speed of static
files - save for the first request.
